Detailed Description

Base classes for single-frame measurement plugins and the associated task.

In single-frame measurement, we assume that detection and probably deblending
have already been run on the same frame, so a `~lsst.afw.table.SourceCatalog`
has already been created with `lsst.afw.detection.Footprint`\ s (which may be
"heavy" — that is, include pixel data). Measurements are generally recorded in
the coordinate system of the image being measured (and all slot-eligible
fields must be), but non-slot fields may be recorded in other coordinate
systems if necessary to avoid information loss (this should, of course, be
indicated in the field documentation).
